Structural geology

The uncertainty in the modeling of the structural geology has a large impact both in reservoir volumes and flow through the reservoir. However due to limited support for handling this uncertainty in standard software, this uncertainty is often ignored. We at NR have worked with stochastic modeling of structural geology since the 1980's.

The methodologies developed at NR are mainly available through the Havana and Cohiba software suites. We also assist customers with running studies of the structural uncertainty.

We have developed a novel algorithm for modeling fault seal within the structural model. This algorithm is available in the newest version of RMS and support fault seal calculations for stair-stepped grids.

In this project we have studied how different cap-rock shapes influence the CO2 storage capacity. Different cap-rock geometries where generated using geostatistical techniques. The storage capacity was evaluated using simple spill-point algorithms and dynamic flow simulations.
